IMPROVEMENT IN LUBRICATORS.

, The S`chedu1e` referred to inthese Letters Patent and, making'part: of the same Be itkn'own that I, DAVID AbAMsoN, of Brennen,

A win Germany, have invented a new and improved Luhricator; and `I do hereby declare that the followingv t is a full, clear, and 'exact description thereof, which fwill enable others skilled in thelartto make and use thesanle, reference being `had to the accompanying drawing forming part of this specification. i

y The drawing represents a verticalv central section of `my improved lnblicator.

This invention relatesto an improvement in that class of lubricator cups in which alpiston is employed Cto receive steam-pressure, for forcing or coagulating material out of the cup. The present invention is -more particularly applicable to locomotives, but may :also be usedon all other engines.l

'It consistsin providing a steamr`entrance through A, in the drawing, representsthe. cup, which is i Q made cylindrical, `or of other suitable form.

. -B isitsrscrew-shank or support, by means of which l it is screwed or` secured bricated.

into the A.machinery to Ahe lu` A cock, O, isittedthrough thisshank, to regulate two or more` longitudinal passages, `u b, through the same, as shown.

Q One of these passages, a,` connects with a pipe, D, `which projects from the bottomofthe cup A, tonear f the cover c of the same, as indicated in the drawing.

The upper end of the pipe, `D is funnel-shaped, to receive` a valve, E,'that is suspended from ascrew, F; This screw Vis fitted through the coverv c, and well packed. Y

The other passage or passages,'b, lead to the perforated bottonr d of the cup, G isa piston, sliding in the cup.r

The lubricating-material is placed into the cylinder A upon the piston G; then, entering the passages b, passes through the bottom d, and' presses against the underside of the piston, tending to force the lubiieating-material out through the pipev D 'and passage a. rlhc area of a being 'smaller than that of b, A-prevents the steam Apressure through a from being stronger than through b, while'it does not prevent the steam from coming iu actual contact with the lubricating-material, which it helps to melt by its head.

lThis lnbricator can be used in a vertical, horizontal, or inclined position, as may he desired.

Having thus described my invention, y I claim asv new and desire tosecure by Letters Patent l 1. The combination, with the cup A, 'of the passage or passages b, and the piston G, sliding onthe tube D, substantially as and-for the purpose described.

2; The. pipe D and passage a, provided in the cup A, tov operate in conjunction -withthe piston G and steampassage b, as set forth.

3. The p ipe D, secured at its lower end in the screw-shank B, and perforated bottom d, and extended up to near top of the cup', and provided with afunnelshaped month, to receive the valve E, as shown and described. c DAVID ADAMSON.
